Shortcuts: Select Input Alt not working

[chfvoigt]

Hi, I have an LG display and assigned keyboard shortcuts to switch the input source, which works really well. Now I tried to create a shortcut to do the same, but when I use the Send DDC action, choose "Input Select Alt" and set the value to "208" or "209", the standard value which work for the keyboard shortcuts, nothing happens. If I use the regular "Input Select", the screen turns black for a second, but as expected the input source is not changed. Is there anything I'm missing? Thanks!

Hi there, sorry, I missed this... 😱

Are you using this keyboard shortcuts section?

If so, Alt modes should simply be there:

If you want to use macOS Shortcuts, sending DDC will not work indeed as Input Select Alt is not really a fully DDC compliant command, it needs a different addressing as well. I recommend creating a "Run Shell Script" action and use the following command:

betterdisplaycli set --ddcAlt=208 --vcp=inputSelectAlt

You can install betterdisplaycli from here: https://github.com/waydabber/betterdisplaycli

Hi @waydabber, that's really helpful! Yes, I had the regular keyboard shortcuts up and running, but was trying to include it in a Shortcut (with capital S). I have already installed betterdisplaycli and will modify the Shortcut later. Problem solved—thanks a lot!
